Abstract

Remote sensing technology application emerges as a useful tool for exploring atmospheric pollution revelation in the last two decade. In this study, we used Aura satellite Ozone Monitoring Instrument (OMI) tropospheric NO2 and pbl SO2 retrieval data (October 2004 – September 2013) to generate a composite spatial map of different seasons over New Delhi National Capital Region (NCR). For surface measurements, we used Central Pollution Control Board (CPCB) NO2 and SO2 data (January 2005 – December 2013). Further, we compared the satellite retrievals data to the surface measurements. A higher NO2 concentration in both OMI and CPCB stations measurements are obtained in winter season followed by summer and minimum in monsoon months. OMI SO2 concentration is higher in monsoon months and almost comparable in summer and winter seasons. We obtained a statistically significant correlation between OMI tropospheric NO2 and CPCB surface measurements.
